To sharpen the saw chain
The cutter
The cutter is the cutting part of the saw chain and has a
cutting tooth (A) and depth gauge (B). The cutting depth
of the cutter is made by the difference in height between
the two, the depth gauge setting (C).
(Fig. 46)
Make sure to correctly sharpen the cutting teeth by
using four important criteria:
•
File angle
(Fig. 47)
•
Cutting angle
(Fig. 48)
•
File position
(Fig. 49)
•
Round file diameter

To sharpen the cutting teeth
Use a round file and a file gauge to sharpen the cutting

teeth. See
on page 21 for information on the recommended
dimension of the file and gauge for the saw chain
installed on your product.
(Fig. 51)
1. Make sure that the saw chain has the correct
tension. A chain without the correct tension moves to
one side does and not sharpen correctly.
2. Use the file on all the teeth on one side. Then use
the file on the cutting teeth from the inner face and
decrease the pressure in the reverse direction.
3. Turn the product on the opposite side and use the
file on the teeth.
4. Use the file to keep all teeth the same length.
Replace a worn saw chain when the length of the
cutting teeth decreases to 4 mm (5/32 in).
To adjust the depth gauge setting

gauge. See
After you sharpen the cutting tooth (A), the adjustment
of the depth gauge (C) will decrease. To keep the best
cutting performance, use a file on the depth gauge (B) to
get the recommended depth gauge adjustment. See
Guide bar and saw chain combinations on page 20 to
find the correct depth gauge adjustment for your chain.
(Fig. 52)
Note: These recommendations are for when the length
of the cutting teeth has not been significantly decreased.
